   Apparently one of the TeaMp0isoN founders was just killed by a US drone
   strike in Syria. Crazy times.
   According to the.. fairly questionable.. article linked above, he was
   #3 on the US kill list, "behind only Jihadi John and ISIS leader Abu
   Bakr al-Baghdadi"! Not bad for a guy most famous for SQL injections.. I
   wonder who took his place on the list.
